Stainless steel plate 9 mm thick perforation
On 2011-03-29 22:41:38
I made a flight with a straight drill for iron, so when I finally tried to try it I could not cut it at all and I quickly broke as soon as I thought I came to sharpen it. I was going to buy a couple of new 17 straight drills for iron that I could buy without buying a couple of new drills for iron so that I could not burn the cutting edge gradually. This is a good deal .... I will not buy anymore.
